Windows 10: Error updating Windows to Creators Update

    Error updating Windows to Creators Update

    Hi! I've already received the notification to update my Windows 10 x64 Home twice. At the end of the process, after several automatic reboots, at the very end there is the "Restoring previous Windows version" message. I've tried all the other methods (Media Creation Tool, Update Manager, ISO from hard disk and from DVD). The result was only the same.

    This was a couple of months ago. From then, I gave up and never received the prompt to update from WU again, apart from regular WU for my W10 version which is AU v1607, Anniversary Update.

    My question is: could it be that it is necessary to leave some space unallocated in system C: drive? I had a 900MB of unallocated space, and just to not waste space I created a new partition for my office files. At the time of the updates there was no unallocated space available. Could it be this the cause?

    ASUS X751L, Intel i7, 8 GB of ram, GEFORCE GTX 950M
    Windows 10 Home Edition x64, v1607 build 14393.1358

    Any advice please?

    Please post a screenshot of your partitions- e.g. Minitool Partition Wizard - a 3rd party program is preferable if you have one.

    Failing that, Disk Management (it won't show one partition if yours uses EFI).

    Please make sure all text is visible in each column.
    To post a screenshot please use the Insert Image icon above your post to the left of the video icon.

    You will need sufficient free space on C:, also best to have at least 500Mb unallocated on your system disk.
    Make sure all unneeded peripherals are disconnected; disable or uninstall any 3rd party AV.

    There are plenty of threads about failed upgrades here- please feel free to browse.

    Also get ready to do a manual upgrade- download the iso and create a bootable Win 10 medium. Guides in the Tutorial section if needed.

    Check your disk- use Hard Disk Sentinel (trial) and post a screenshot of its GUI.

    What antivirus/antimalware programs are you running? Have you tried the upgrade with them disabled, or even uninstalled?

    Unfortunately, sometimes the Windows installation just breaks and will refuse to upgrade. A clean install fixes it and usually will go for at least two or three major upgrades after that.

    It is necessary to have free space available in the Windows partition - 20 GB should always be sufficient. But it is not necessary to have unallocated space on the drive. Very few computers have unallocated space on their hard drives/SSDs.

    Why? I have never seen a retail manufacturer sell a computer with unallocated space on the system disk.

    Sorry, I have Minitool Partition Wizard Bootable Disk only, so I took a shot with my smartphone. I hope the text is readable.
    In addition I try to add a scheme of my partition table made with notepad:

    Partition Capacity Used Unused File Sys Type
    *:SYSTEM 100.00MB 29.00MB 70.11MB FAT32 GPT (EFI System)
    C:MS OFFICE 899.00MB 43.36MB 855.63MB NTFS GPT (Data Partition)
    *: 128.00MB 128.00MB 0MB Other GPT (Reserved Partition)
    D:SISTEMA 149.22GB 50.40GB 98.82GB NTFS GPT (Data Partition)
    *: 798.00MB 12.84MB 785.00MB NTFS GPT (Recovery Partition)
    EATI 780.41GB 324.28GB 465.00GB NTFS GPT (Data Partition)

    ____________________________________________________________________________________________________ ________

    So, to respond to the other questions, my security software installed are:

    Avast Antivirus Free (only File, Web and Mail Shield activated, all other crap deactivated)
    Comodo Firewall (only firewall module activated - Auto-Containment, HIPS, VirusScope, Web Filter all disabled)
    Malwarebytes' Antimalware Free without real time protection - so it should not interfere with the update process.

    I hadn't tried to disable my antivirus before, I'll try next time. Of course I disconnected all my usb devices.

    Thank you guys. What can be guessed from my partition table?

    The "Other" partition of 128 mb should be the second partition just after the EFI System Partition, but I don't think that is the problem. I would start by uninstalling all antivirus programs except for Windows defender.

    Comodo Firewall is known to cause trouble whilst trying to update to CU.

    Thank you for your suggestions, guys. I'll remove Comodo and avast! next time, and report back what happens! Cheers, Alpha.
